[Q] Today update ? - Galaxy S II Q&A, Help & Troubleshooting

hello , today i receive ota update in my galaxy s2; i download files 13mb
but after restart a message appears : can not install update try with Kies , any information about this update ?

Your actual ROM version? Your country? Try to use Kies and tell us the before and after version so we can understand it much better.

Thank Julian
my actual ROM : android 4.0.4 I9100XXLQ6 - My country Algeria ; i try with KIES but no update

Are you using a custom kernel? That can be the cause of a failed update.

Hello, flash back to an unmodified rom. Flash the whole rom and do not root it or flash a custom kernel over it.

thank you ; can i unrooted it without flash ?

I wouldn't recommend flashing a stock 4.0.4 kernel though unless you're sure you're not going to need to do a wipe.

Just use odin.. Or root your 2.3.5 rom and go for a custom rom (that is better)

How to know my original Kernel Version?

Hi,
I just rooted my SGS2 using the following kernel: CF-Root-SGS2_XX_XEO_LPQ-PROPER-v5.4-CWM5, the problem is forgot to write down my original data, so is there a way to know it?
and does rooting the phone also changes the Build Number and Baseband Version?
Here is my current data:

"lightbox_toggle_sidebar": "Toggle sidebar"
}
search for the correct stock rom..try here http://forum.xda-developers.com/showthread.php?t=1544487 anyway, why do u want that for?
build and baseband are not modified by the kernel

Well I'm afraid the kernel I used won't be compatible with the phone, isn't that right?
I'm sorry I'm new to this

If you want to unroot all you have to do is go to www.sammobile.com and download the stock firmware and flash through Odin. You will get your stock Kernel back. So don't worry, try some aftermarket kernels
Sent from my GT-P7510 using xda premium
if it isn't compatible, the phone won't turn on, or pass the Samsunggalaxy GT-I9100 screen. so don't be afraid. just in case, and to be safe, if your phone is working OK right now, you should make a nandroid backup in CWMR (volumeup+home button+power button). and then you can mess with anything you want (except stock kernels made from 9 of july of 2012 to now) and there will be almost no problems
you can try any kernel...not every kernel works fine in terms of battery life and hardware manage. even though is the one that came with your custom rom. the same is for modem(baseband)

First use Triangle Away to reset the flash counter and then use Check Fus to get the latest firmware for your phone. Afterwards flash the same using Odin.
I reseted it first time flashing rom so its already 0
Invalid HIDSWVER with Check fus

Oops, I missed that, sorry. No it will not come back as long as you flash stock firmware only.

[Q] ] Android 4.1.2 root

Can you get root and have everything stock(firmware, kernel)?
If I install siyah kernel or any other kernel you don't get OTA. I want to have root and still get OTA.

I don't think you will get OTA after installing CMW. If someone tested post here.
It's a temp recovery, don't think it would matter.

Isn't there a method to get root through ADB? So I can keep everything stock.
Don't think so.

Cf-root is probably the closest to stock kernel with root. And as far as I know, you do get ota updates, but you'll obviously lose root once you update via ota, kies, etc.

As above and monitor XDA/Samfirmware for updates and flash latest stock roms through mobile odin.

1) install kies on your desktop/laptop.
2) enable usb debugging in developer options in your phone.
